Agro Ship

Common classification for spacecraft capable of the procreation of any edible agro foodstuffs needed in any sort of convoy or Fleet for long periods of time. These crafts have translucent hull plates interconnected in a structural enforcement grid of a type, which allow the plants to receive the necessary sunlight from a nearby star or some other stellar formation to achieve the state of photosynthesis. Of course, artificial lighting is, apparently, also an important function of these agro ships. (The Magnificent Warriors) Albeit the viewer never truly gets to see them powered up in such a manner that would reap the benefits of a star.

Agro ships are unarmed, but can withstand an assault for some period of time. (The Magnificent Warriors)

The Galactica's Fleet had three such agro ships; two of which had been destroyed by the Cylons and the third one (the Agro Ship 9) experiencing a hull breach via a destroyed airlock. We can presume that this remaining agro ship is the last of her kind, and produces three times as many foodstuffs as needed within the entire Fleet. (The Magnificent Warriors)

Notes

The agro ships are reuses of the spacecraft from Silent Running, a Universal/MCA movie that special effects guru John Dykstra worked on a few years prior to Battlestar Galactica.

The same exact shots of the agro ships destructions in "The Magnificent Warriors" were reused in the Galactica 1980 episode, "The Space Croppers". Thus continuing Battlestar's regrettable, near-laughable tradition of continual reuse of stock footage.
